Abstract
An inlet valve reconditioning process is disclosed which includes soaking the inlet valve, as removed from a valve body, in a cleaning solution for a period of time sufficient to loosen foreign material from all exposed surfaces of the valve, disassembling the valve into its component parts, cleaning the various component parts with the cleaning solution, reaming cavities formed in the male and female members of the valve, cleaning the valve seat, relapping the valve stem and reassembling the inlet valve into the valve body. The valve can be reused for its intended purposes within such a valve body without loss of either efficiency or durability.
